The Schedule referred to in these Letters Patent and making pm of thesame.

Be it known that 1, CHARLES Lours FnnIsoHMANN,

.of the city'of Washington, in the District of Columbia,"

have invented a new and improved Process of Extracting Oil fromCotton-Seeds and other oleaginous seeds;

7 and I dohereby declare that the following is afull and exactdescription of the process;

To enable others, skilledin the art to make and use my invention, 1 willdescribe the process. The seeds from which the oil is to be extractedare either in layers or heaps, and sprinkled overiwith a strong solutionof an alkaline lye, until every seed is brought in contact with the lye.The heaps or layersare left undisturbed till the'teIfi-j perature ofthe" seeds begin to rise, when fthey are turned over, in order to lowerthe temperature and to prevent decomposition of the oil. The seedsmustbe turned every time the temperature rises, and it is thus,continued till the husks become. perfectly softened.

When the husks havearrived atthe proper state of mollification, they arecrushed to a fine pulp,be'tween rollers, and the pulp is again placed inlayers or heaps,

and is thoroughly impregnated with a-weaker lye.

' I This lye is applied warm, in order that the combination with the oilmay be accelerated. When this cornbina tiou hasbeenattained, the pulp isnow placed in vats, which are provided with perforated bottoms, and weakwarm alkaline solutions are passed through the pulp until all theoleaginous, matter is washed from it.

The lye which has passed through the pulp is collected in fiat vats,where the separation of the saponaceouscombination takes place. It risesgradually,

when lefi undisturbed for sometime, to the top. This phuric acid, inorder to obtain the oil.

The macerated pulp is pressed, and all the liquid separatedfrornit,lwhen it can be used for manure. i What I claim as my'invention,and desire tosecure by Letters Patent, '19-.

The *process, substantially as herein described, of extracting the oilfrom seeds.
